SEA-ANCHOR.

Specification of Letters Patent.

Patented April 30, 1907.

T 11/ who/)2 it nuty concern.-

Be it known that I, F REDERIGK RoUsn, a citizen of the United States, and a resident of Honolulu, in the county of Oahu, Hawaii, have invented a new and Improved Sea- Anchor, of which the following is a full, clear, and exact description.

My invention relates prin'iarily to a sea anchor or drag, fitted with a peculiarly arranged oil reservoir by means of which not only may the vessels head be kept to the wind while lying to, but oil distributed to windward of the vessel, thus breaking the seas and enabling the vessel to ride out a gale with comparative ease.

The invention also resides in various other features of major or minor importance, among which may be enumerated the peculiar construction enabling the entire rig to be compactly folded for stowage when not in use.

Reference is to be had to the accompanying drawings which illustrate as an example the preferred embodiment of my invention, in which. drawings Figure 1 is an elevational view of the sea anchor in operative adjustment Fig. 2 is a side view of the same Fig. 3 is a view showing the anchor folded; and Figs. at and 5 are enlarged details illustrating the joint be tween two members of the frame.

The drag or sea anchor proper is preferably triangular in form, and consists of a section of canvas or its equivalent laced at its edges to two side rods 11 and a top red 12, by a rope or cord 10. The rods 11 extend downward converging toward each other, and are joined together by a pin 14 which also holds a shackle 15, to which shackle a grappling anchor or kedge 16 may be connected by a suitable chain, if desired. The upper ends of the rods 11 are joined to links 17, and these are respectively pivoted to the ends of a eylindric oil tank 18. The top red 12 is connected to the under side of the oil tank by means of eye-bolts 19, as shown.

The oil tank 18 is provided on its under side with oil discharging openings 20 which may when the apparatus is not in use he closed by screw plugs, as indicated by the broken lines in Fig. 1. The tank is provided at its top with a filling opening closed by a plug 21, and this plug is provided with a vent and screw closure 22, as shown. Joined to the three corners of the frame of the anchor is a bridle 23, and this is joined by a swivel 2 1 to the anchor line which when the device is in use is made fast on the bows of the vessel.

When the apparatus is not in use it may be folded as shown in Fig. 3, thus adapting it for compact stowage. In doing this the belt 1 1 is removed, thus disconnecting the lower ends from the rods 11 and allmving said rods to be swung-in alongside of the tank 18, the lacing of the canvas section 1.0 to said rods being for this purpose released. hen the apparatus is to be employed the rods 11 are moved outward to a position shown in Fig. 1 and joined to the bolt 14-, after which the canvas section 10 is laced to the rods and the plugs of the discharge openings 20 having been removed the apparatus is thrown overboard. Tlae anchor line 15 is made fast to the bows of the vessel, which drifting to leeward from the anchor is held head up to the sea. The anchor 16 causes the canvas section or drag proper to project downward from the oil tank which will float on the surface of the water. The oil steadily escaping from the openings 20 forms a film over the surface of the water and prevents the 00aming or breaking of the seas, thus enabling the vessel to safely ride out the storm. 4

Having thus described the preferred form of my invention, what I actually claim. and desire to secure by Letters Patent is:

1 A sea anchor or drag comprising a cylindrical oil reservoir, links pivotally connected with the ends of the reservoir, rods pivotally connected to the links and to each other, a rod supported by the reservoir and forming with the other rods a triangular frame, a section of canvas rcmovably connected with the frame, a bridle connected with the corners of the frame, and a grapple connected with the lower corner of the said frame.

- 2. The combination of an oil reservoir, a sea anchor or drag connected to and depending from the same, a grappling hook suspended from the lower part of the drag, and means for connecting said parts with a vessel.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

FREDERICK ROUSE.
